By some reason mozjs52 wants to get installed and fails:

Could be he problem comes from these lines in config.log:

These are tests on lower case strings, but GCC defines UPPER CASE STRINGS. So configure has to state: ERROR: Target C compiler target CPU (unknown) does not match --target CPU (powerpc). Some more files seem to think it's FORTRAN time in reverse:

[ballapete (Peter "Pete" Dyballa)]

Looking in Leopard into mozjs-52.6.0gnome1/js/src/obj/config.log it seems rather that GCC has #defined lower case strings, but not ppc or __powerpc__. Instead it has __ppc__:

The Mozilla folks recommend to use mozjs60 because version 52 is not maintained anymore. (And their support starts with macOS 10.9. Of course.)

The option to patch file is beyond my knowledge. I have no how idea how Python works and how I could debug to see which files are used, that might need a patch or two…

[kencu (Ken)]

I don't know if there will be much luck getting this to build on 10.4 or 10.5 PPC. It's not easy to do, I suspect.

A fairly recent (45, I think) version of mozjs is built in TenFourFox but that took some serious attention.

May I ask if you have narrowed down what you're trying to install (or upgrade) that is pulling this in? Maybe we could figure out how to get around the dependency instead.

It's policykit.

[kencu (Ken)]

Yeah -- for now you will need to roll back to the last version before the update to 0.115, because it appears 0.115 needs mozjs52.

And you'll need to peg at that version, maybe forever, on PPC.

mozjs60 has the same problem. I've updated the upstream bug report with this information and some hints about how they might solve it.

Update: Clang defined those macros, not Python. Sorry for the noise.

I don't believe the macros the script looks for are GCC macros; they seem to be defined by python. I tested GCC v4.2-apple, v4.9-mp, v5-mp, v6-mp and v7-mp and none of them defined those macros. I'm still investigating, but right now it looks like there's no issue with Mozilla's configure script, but there's an incompatibility with Apple's python2.7 while Macports' python2.7 works.

[khepler]

For what it's worth, the pre-processor macros to be checked are defined on lines 80 and 81 of mozjs-52.6.0gnome1/python/mozbuild/mozbuild/configure/constants.py:

 71: # The order of those checks matter
 72: CPU_preprocessor_checks = OrderedDict((
 73:     ('x86', '__i386__ || _M_IX86'),
 74:     ('x86_64', '__x86_64__ || _M_X64'),
 75:     ('arm', '__arm__ || _M_ARM'),
 76:     ('aarch64', '__aarch64__'),
 77:     ('ia64', '__ia64__'),
 78:     ('s390x', '__s390x__'),
 79:     ('s390', '__s390__'),
 80:     ('ppc64', '__powerpc64__'),
 81:     ('ppc', '__powerpc__'),
 82:     ('Alpha', '__alpha__'),
 83:     ('hppa', '__hppa__'),
 84:     ('sparc64', '__sparc__ && __arch64__'),
 85:     ('sparc', '__sparc__'),
 86:     ('mips64', '__mips64'),
 87:     ('mips32', '__mips__'),
 88: ))

Setting the 'ppc64' and 'ppc' values to '__powerpc64__ || __POWERPC64__' and '__powerpc__ || __POWERPC__' allows the configure script to succeed, but the build later fails trying to pass -stdlib=libc++ to g++-mp-6:

[kencu (Ken)]

I have some progress to report on getting this to build on Tiger PPC, but it's not yet working to build through to the end (and nothing is actually tested yet, of course). But if you're motivated and have some skills and interest, this will probably be helpful. I'll upload my WIP to date. The error at the moment comes because code to handle PPC on Darwin is not written for

js/src/wasm/WasmSignalHandlers.cpp

and will need to be added.

Error:

[ballapete (Peter "Pete" Dyballa)]

I do not have that much time right now.

[ballapete (Peter "Pete" Dyballa)]

The memalign problem seems to be well known, because a few patch files for this problem exist: /opt/mports/trunk/dports/devel/jemalloc/files/patch-memalign.diff /opt/mports/trunk/dports/math/fftw-3/files/leopard-no-memalign.patch /opt/mports/trunk/dports/net/libtorrent/files/no_posix_memalign.patch /opt/mports/trunk/dports/net/libtorrent-devel/files/no_posix_memalign.patch. Maybe they contain something useful. (I do not understand the problem.)

[dbevans (David B. Evans)]

Will leave this to the various powerpc devotees to work out. Seems like @kencu has isolated the problem at least. But I'm afraid a solution is not likely to be forthcoming in the near future unless someone with access to the target hardware is able to put some time into this.

[dbevans (David B. Evans)]

By the way, newer GNOME ports that use this port are indeed moving to mozjs60. Updating dependents of mozjs52 may be the best solution.

[ballapete (Peter "Pete" Dyballa)]

Replying to dbevans:

Times has come! (Who said this?) The weather motivates to stay at home instead of exploring the world of creeks for Wikipedia. And my harvest (apple®s and walnaut®s) is almost brought in. So I can perform a lot of tests. On PPC hardware (7447A) in Leopard (Mac OS X 10.5.8) and Tiger (Mac OS X 10.4.11).

[ryandesign (Ryan Carsten Schmidt)]

Has duplicate #61360.

[stevenptimms]

Replying to kencu:

Yeah -- for now you will need to roll back to the last version before the update to 0.115, because it appears 0.115 needs mozjs52.

And you'll need to peg at that version, maybe forever, on PPC.

Could someone please tell me the command required for me to peg this older version? Thank you

[kencu (Ken)]

to "peg" a port in MacPorts is easy but not encouraged, so there is not one command like "peg" to do it.

The method is to create a folder that is structured like the ports tree folder, add ports in there you want modified from the main macports offerings, and then configure MacPorts to check your folder first when looking for ports. It takes less than two minutes to do this. The full instructions are here <​https://guide.macports.org/chunked/development.local-repositories.html>.

I have been doing this for years. Mine is here <​https://github.com/kencu/LeopardPorts/> for an example of what I'm using. You can use that as an idea. Specifically for policykit, my peg is here <​https://github.com/kencu/LeopardPorts/tree/master/security/policykit>.

MPorts is much more supportive of older systems than other pkg managers for Mac...a few of us like doing this.

You'll be able to get your system running many many ports (I have thousands installed), but not every port is practical to fix.

[kencu (Ken)]

I have a WIP for building mozjs52 on 10.5 PPC going here <​https://github.com/kencu/macports-ports/tree/mozjs52PPC/lang/mozjs52>.

At present, it builds through to finishing the build for the mozjs52 dylib, but there are link errors due to multiply defined symbols in the JIT code.

I think the next step is to either sort out how to disable ION / JIT (the --disable-ion command is not seeming to do it...), or better to merge in some of the mozjs fixes for osxppc from TenFourFox and actually try to get that enabled.

The patch file might also be useful for getting mozjs52 building on Intel systems < 10.6 -- I haven't tried doing that as yet.

[evanmiller (Evan Miller)]

Hi all, I have been working to get mozjs60 to build on a G3 running 10.4.11. Here is what I have so far, building off of the collected efforts in this ticket: ​https://github.com/evanmiller/macports-ports/commit/47ba685438f323287f6adbb1e623d0e575d02b03

Builds on my machine (finally) but may need some updates to work on PPC64 and 10.5. It compiles and installs, but the js60 command doesn't print anything for some reason. In addition, because I removed some static_asserts it would not surprise me if there are some crashes somewhere. The js60-config command works at least. Thought I'd collect some feedback here before opening a pull request.

[kencu (Ken)]

well done!

the next step would be to take a stab at running the test suite, and see what comes from that. Would be good to run it first on a working Intel system to see what to expect.

I run the js test suite on TenFourFox like this, for a starting point perhaps:

run the tests in js/src/jit-test
./jit_test.py -f ../../../obj-ff-dbg/dist/bin/js

[kencu (Ken)]

from the top level of the mozjs60 build tree, I ran this on 10.6.8 (Intel) and it seems to be testing as expected:

sudo chmod -R a+rw ./*
/opt/local/bin/python2.7 js/src/tests/jstests.py js/src/obj/js/src/js

This may not be 100% the perfect way to run the mozjs test suite, as I just googled around until i found something that looked workable, but it's running on my system at the moment at least.

[kencu (Ken)]

Here is the final bit of output of the test suite on 10.6.8 running 64 bit mozjs60:

If I read this right, there are two unexpected failures out of 30,600 tests. That is pretty good. The details on the two unexpected failures are available here, and appear to have something to do with PST time vs PDT time. I can live with that.

[kencu (Ken)]

I haven't debugged at all.

[kencu (Ken)]

Well, we are definitely further ahead than once we were.

XUL test condition 'Android' would seem to point to some confusion in platform selection.

In my repos I have pegged back to mozjs17 and software that needed that:

​https://github.com/kencu/TigerPorts/tree/master/lang/mozjs17

and I haven't noticed any issues, but TBH I have not even tried to run the test suite there.

We certainly don't need a 100% pass on anything, but we would need to have some indication that it works at all before we commit it.

[kencu (Ken)]

mozjs17 does quite well on Tiger Intel:

[evanmiller (Evan Miller)]

Quick update here after some fooling around this afternoon. I found a "magic" compiler flag that let me restore the static_asserts in the code base that I had commented out earlier: -mone-byte-bool. The bool type is a 4-byte integer by default on Tiger/PPC, but a 1-byte char on Intel. This results in different layout and sizes when bools are packed into structs. But passing -mone-byte-bool to GCC on PPC results in an Intel-compatible bool size, and should fix some instances of highly optimized code. (Of course, as the ​docs note, it could also break ABI compatibility with external libraries that expose bools.)

Unfortunately the js60 shell still isn't starting for me on Tiger, so nothing else to report for now.

[kencu (Ken)]

there exists a type called "Boolean" in mactypes that might possibly be useful.

Boolean         Mac OS historic type, sizeof(Boolean)==1

there are also pragmas available that affect struct packing that are often used in code that interacts with system libraries might prove relevant

be great if this worked! was there something in mozjs17 (builds and works on ppc) that was removed later?

also the TenFourFox code had a lot of tweaks done for mozjs by Cameron and there could be pearls in there.

[evanmiller (Evan Miller)]

Some progress to report - I tracked down the Tiger issues to ICU failing to initialize (u_init() failing) on that platform. I didn't dig any further into it, but configuring --without-intl-api solved it, and I finally get a usable shell on Tiger/PPC:

$ js60
js> 1+1
2

Basic tests are looking good, but the full suite may take a while to run. Will open a PR later this morning if everything looks OK.

Bigger picture: It looks like the only MP consumers of mozjs are gjs (mozjs52) and policykit (mozjs60). It looks like their latest versions both require mozjs78. So rather than backport this work to mozjs52, the time is likely better spent forward-porting to mozjs78 and then updating the relevant packages.

Pull request over here... Leopard testers needed! ​https://github.com/macports/macports-ports/pull/12186

[ballapete (Peter "Pete" Dyballa)]

I tried to build mozjs60 on PPC Leopard by adding a line

onfigure.cflags-append -mone-byte-bool

in Portfile. Building fails because the processor type seems to be unknown:

@ballapete Please try the complete Portfile and patch set in the Pull Request linked above.

Replying to evanmiller:

@ballapete Please try the complete Portfile and patch set in the Pull Request linked above.

I think I see now that the interface provides a "Files changed" section from which I should copy.

[ballapete (Peter "Pete" Dyballa)]

Replying to evanmiller: How can I download those patches as files in an appropriate format and with the names that will be used in the new version of Portfile? (I am neither developer nor GitHub user.)

[evanmiller (Evan Miller)]

You can download the whole tree here:

​https://github.com/evanmiller/macports-ports/archive/refs/heads/mozjs60-powerpc.zip

Open up the "lang" folder in the download.

In another Finder window, navigate to /opt/local/var/macports/sources/rsync.macports.org/ports/lang

Copy mozjs60 in the downloaded "lang" folder to the MacPorts "lang" folder, replacing the MacPorts "mozjs60" folder.

Then "sudo port install mozjs60" in the Terminal.

If it installs, run js60 in the Terminal and type an expression (e.g. 1+1)

If it does not install, report any errors here.

Thanks!

[ballapete (Peter "Pete" Dyballa)]

Replying to evanmiller:

Sorry Evan! Probably I used the wrong words before. Corrected version: I don't know how to use GitHub with TenFourFox and I do not want to download another ½ GB and fool around with it and I do not know how to put the lang folder into a place that MacPorts would recognise – and when! For me it's much easier to get some kB of one or more patch files, programme or patch Portfile accordingly, and then run port -vds build mozjs60 once more.

How can I get the set of patch files in text format on PPC Leopard? If there is a way to press the right buttons of GitHub, and you could tell it, then I could try to fetch them myself. (I am European. And I think small is much bigger than Texas. And it's democratic here: exactly every person one vote.)

[evanmiller (Evan Miller)]

Ok, here is a downloadable patch file:

​https://github.com/evanmiller/macports-ports/commit/c2135be703a92eec7edd1176f3b7a63c7ec85722.diff

Then:

sudo port sync # To ensure a fresh Portfile
cd /opt/local/var/macports/sources/rsync.macports.org/macports/release/tarballs/ports
sudo -u macports patch -p1 < ~/Desktop/c2135be703a92eec7edd1176f3b7a63c7ec85722.diff
sudo port build mozjs60

[kencu (Ken)]

looking good! The test suite does surprisingly well on a TigerG5, I thought. Only two failures in the regular tests out of 30,232 tests, and 2 failures in the jit out of 6,260 tests. So that is beyond hope, really.

Really well done, thanks.

Replying to evanmiller: cd `port file mozjs60`/../../.. would make the change of working directory indepent of the RSYNC server. The configure phase is over and the build started. How many days will it take to compile ½ GB of source code? (PowerBook G4 with 1.5 GHz PowerPC 7447A)

[evanmiller (Evan Miller)]

On my G3 it took... 8 hours, I think? So maybe half that on G4?

It sounds like the diff I provided will fail on Leopard so you may want to restart with an updated one:

​https://github.com/macports/macports-ports/commit/50cdf084768436a421e2c6d05e995d122bc93bca.diff

Or do a port sync tonight/tomorrow - looks like @kencu has just merged the final version to master and has closed this ticket.

[ballapete (Peter "Pete" Dyballa)]

I'll let it build silently at reduced CPU speed over night and shall see tomorrow morning, in nine hours, whether I could make -k check in /opt/local/var/macports/build/_opt_local_var_macports_sources_nue.de.rsync.macports.org_macports_release_tarballs_ports_lang_mozjs60/mozjs60/work/mozjs-60.8.0/js/src/obj. I presume that's the proper place…

[kencu (Ken)]

That is not how you run the tests for this, Pete. You do it as I outlined above.

But you don't have to do it -- I did them all on PPC over the last 24 hours, and posted the results above.

We could add an official "test" phase to this port-- but that's for next round.

@ballapete Thanks for the update. What port were you originally trying to install? When ​#12192 is merged, there should no longer be a need for mozjs52.

[ballapete (Peter "Pete" Dyballa)]

Replying to evanmiller:

It was policykit.

[evanmiller (Evan Miller)]

@ballapete Are you all set then? Current policykit should be using mozjs60.

[ballapete (Peter "Pete" Dyballa)]

Replying to evanmiller:

Yes, thank you!

[evanmiller (Evan Miller)]

Before anyone gets too excited for mozjs68 / mozjs78: It looks like everything after mozjs60 requires a Rust compiler, and we don’t have Rust on PPC. So this is the end of the line for now.

mozjs52 is no longer used by any other ports, so this ticket can be closed.
